Greater design capacity-hydrocarbon gas separation process
Patent
·
OSTI ID:6337147
A process is claimed for recovery of components of volatile gas containing methane and heavier components, by a cryogenic process, cooling the incoming raw gas and separating the desired products by distillation. The feed gas is then divided into two streams, one being primarily liquid, which is expanded to lower the pressure and then fed into the demethanizer tower at a selected point, and the other stream, being primarily gas, is divided and expanded and discharged into the demethanizer at selected positions to place the streams in the demethanizer to accomplish maximum separation and recovery of the desired components in either an ethane recovery mode or an ethane rejection mode, the pressures and temperatures of the demethanizer being adjustable for either.
